The plant commonly referred to as Purple Ivy, or Purple Passion Vine, is Gynura aurantiaca, a tropical perennial native to Southeast Asia. It belongs to the Asteraceae family, which also includes daisies and sunflowers. The plant’s distinct appearance comes from fine, dense, purple hairs, or trichomes, that cover its deep green leaves and stems. This gives the foliage a soft, velvety texture and a shimmering, iridescent purple hue, making it a highly sought-after houseplant.
Essential Growing Conditions
Successful cultivation of Gynura aurantiaca depends heavily on light exposure, as the vibrant purple coloration is directly influenced by light intensity. The plant thrives in bright, indirect light. Placing it near an east or south-facing window, where it receives gentle morning sun, is ideal. Insufficient light causes stems to elongate and the purple trichomes to fade, resulting in duller, greener leaves. Conversely, too much direct sunlight can quickly scorch the delicate foliage.
The ideal growing medium is a well-draining, airy potting mix that allows for proper root aeration. A standard indoor potting mix works well, but incorporating materials like perlite or sand enhances drainage. Good drainage is necessary to prevent soil compaction and subsequent root issues.
As a tropical plant, the Purple Passion Vine prefers warm temperatures, ideally between 60°F and 75°F (15°C to 24°C). It is sensitive to cold and must be kept away from sudden temperature fluctuations or drafts. Moderate to high humidity is also appreciated. To increase ambient moisture, place the pot on a pebble tray filled with water, allowing evaporation to surround the foliage.
Watering and Routine Maintenance
Careful watering is essential to maintain the plant’s health. The soil must be allowed to dry out slightly between applications. Water thoroughly only when the top inch or two of the soil feels dry to the touch. Overwatering is a common issue that quickly leads to root rot, to which this plant is susceptible.
Watering from the base is preferred, as the foliage should be kept dry to prevent fungal problems. During the active growing season (spring and summer), the plant benefits from regular feeding. Apply a balanced liquid houseplant fertilizer, diluted to half-strength, every four to six weeks to support growth and color intensity. Reduce or stop fertilization entirely during the slower growth period of fall and winter.
Regular pruning encourages a bushier growth habit and prevents stems from becoming sparse or “leggy.” Pinching back the stem tips encourages the plant to branch out, resulting in a denser form. The plant produces clusters of small, orange-yellow flowers, typically in the fall, which should be removed. Removing the flowers directs the plant’s energy back into producing vibrant foliage.
Propagation and Pest Control
The most successful method for creating new Purple Passion Plants is through stem cuttings. Take cuttings from healthy stems, ensuring each piece has at least two to three leaf nodes. The best time to propagate is during the spring or early summer when the plant is actively growing.
Cuttings can be rooted in a glass of water or placed directly into a moist, well-draining potting mix. When rooting in soil, removing the lower leaves and dipping the cut end into rooting hormone increases the success rate. Place cuttings in a bright, warm location and keep them consistently moist until roots establish, which usually takes several weeks.
Gynura aurantiaca is susceptible to common houseplant pests, including spider mites, mealybugs, and aphids, which target the soft foliage and stems. Inspecting the undersides of the leaves regularly allows for early detection. Simple treatment involves wiping the leaves with a damp cloth or cotton swab dipped in rubbing alcohol for mealybugs, or applying a gentle insecticidal soap to the affected areas.
